Answer 1

The error message indicates the problem fairly clearly.  _feed_list is defined as a ComboBox in your first line of code.  You are passing that as an argument in your populate(_feed_list) line of code.  However, the populate function is expecting an XMLList object to be passed, not a ComboBox.
You probably really mean to be using...
          populate(feed_items);
since that is the only XMLList to be found
